Alkaline Water vs Mineral Water – Complete Comparison
Both alkaline water and mineral water are considered healthier than plain tap water — but which one is actually better? Let's find out.
Mineral Water
Mineral water contains naturally occurring minerals like calcium, magnesium, and sulfates. Packaged mineral water brands in India (Bisleri, Kinley, Aquafina) have a pH of 6.5–7.5 — mostly neutral to slightly acidic.
Alkaline Water
Alkaline water has a pH of 8–9.5, contains essential minerals, and provides antioxidant properties. When produced by a quality alkaline RO purifier, it offers controlled and consistent mineral content.
Key Differences
pH: Mineral water is neutral (7±), alkaline water is 8.5–9.5. Antioxidants: Mineral water has none; alkaline water has high antioxidant power (negative ORP). Cost: Mineral water costs ₹20–30/litre ongoing; alkaline water costs ₹0.50–1/litre once you have the purifier. Plastic Waste: Mineral water creates massive plastic waste; alkaline purifiers are eco-friendly.
Verdict
Alkaline water wins in every category — better pH, more benefits, lower long-term cost, and zero plastic waste. Investing in an Alkin Water Alkaline RO Purifier pays for itself within months compared to buying mineral water bottles.
